EXCAVATO R.

srnorslca'rron forming part of Letters PatentNo. 519,342, dated May 8,1894.

To all whom it may concern.-

Be it known that 1, JOHN OIE, of Marshall,

in the county of Harrison and State of Texas,

' I The object of the invention is to provide an have invented certain new and useful Improvements in Excavators; and I do hereby declare that the following isa full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and numerals of reference marked theron, which form part of this specification. p l

This invention relates to certain improve:

ments in excavating and grading apparatus.

improved apparatus whereby earth can be shifted quickly and economically from one point to anotherand can be readily and easily employed for such purposes as building embankments or levees or for excavating exaway of the apparatus, as shown in Fig. 2. p

The invention relates to that class of excavatlng or grading machines where a traveling cable is employed which moves over the portion of ground being operated upon and carries or propels suitable excavating or dig ging means, such as scrapers.

In the drawings the reference letter a, ind icates a suitable platform preferably mou nted on a truck which travels on rails 19', located along one side of the ground to be excavated. On the opposite side of the ground to be excavated suitable rails or a track 6, is arrangedon which a truck I), is located opposite the platform or truck a. The endless cable 70, travels over the ground between the tracks I) ande, and is supported by said trucks or platforms 0. and b. This truck 19*, at one end is counterweighted by suitable means such as a large tank f, filled with water. The opposite end of the truck is provided with an overhanging frame carrying the horizontal return or idler pulley j, mounted upon asuitable vertical shaft. This pulley forms the return for and assists in support ing the (33.131675.

The truck or movable platform a, is provided with the vertical frame h, suitably braced and extending up a distance above the platform.

0, indicates a horizontal drive shaft sup ported by the lower portion of the upright frame h, and mounted in suitable bearings. Suitable means can be employed to drive said shaft such asian engine (not shown) located on the platform or an engine located at a distance and geared by suitable means to said shaft. This shaft is provided with a worm p, meshing with a worm wheel m, on an upright shaft n, suitablymounted in a frame carried by the said platform.

a 5, indicates a grooved (or the like) pulley rigid on the shaft 11., around which the cable is, passes and by which it is driven. This shaft m, is strongly mounted so as to stand great strain. The cable 10, and the pulley 'L, are arranged above the incline q, supported by suitable beams and extending laterally anddownwardly and a distance beyond the platform or truck proper and upwardly to a distance above the said platform properso that the dirt excavating or carrying means, such as scrapers Z, suitably attached to and drawn by the cable can be filled with earth between the truck I), and the incline q, of truck a, and will then be drawn up the incline g, bythe cable. On one side of the pulley 1 or beneath one side of the traveling cable the incline q, is provided with an opening, preferably having supports across 6, indicates a suitable conveyor located beneath the grate or opening 7', in the incline platform to catch the dirt falling. therethrough. This conveyer is of any suitable construction, preferably an endless belt conveyer, such as shown, mounted on the end pulleys and driven by any suitable means such as a belt 3, to one of the con veyer shafts from a shaft 5, suitably mounted in the truck beneath the incline platform and connected by a belt 4, with the main drive shaft 0. The upper length or portion of the conveyer t, preferably travels upwardly and discharges the dirt from thescrapers onto the lower end of a conveyer 6, mounted in the beams or frames u, which are pivotally joined at their lower ends to the platform or'truck so that the conveyer 6, by means of the beams a, can be raisedand lowered to convey the dirt to a considerable distance or to any height desired. 1 This conveyer 6, is controlled and raised and lowered by means of the strong cables 70, secured to the outer ends of the beams u, and carried over the upper ends of the uprights w, of frame 72 and from thence downwardly to suitable windlasses w, or the like secured in the inner portion of the truck or platform a. It will thus be seen that the dirt excavated fromthe portion of land between the two traveling trucks is dumped on to the conveyer t, and then on to the conveyer 6, which can dump the earth into any kind of a vehicle desired or upon an embankment or levee, so that as the bank increases in height conveyer 6, can be raised so as to drop the earth at a greater elevation.

The scrapers can be dumped by hand onto the grate 4, or means not here shown can be provided to automatically dump the scrapers. I

It will be observed that the invention is very cheap, simple and durable in construct tion in comparison with the amount of work capable of being performed. It is also evident that the conveyer 6, can be dispensed with if desired and the conveyer t, can be utilized to dump the earth into vehicles or for conveying it off. The inner end of the conveyer 6, is mounted on the same shaft as the pulley of the bolts 4 and 3, so 'that the conveyer 6, is driven from the main shaft 0. It will also be observed that as the work of excavating continues the trucks at and b can be moved along their respective tracks.

It is evidentthat various changes might be made in the forms, arrangements and constructions of parts described without departing from the spirit and scope of my invention; hence I do not wish to limit myself to the exact constructions herein set forth, but consider myself entitled to all such changes as fall within the spirit and scope of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The herein described excavating apparatus comprising the movable truck a carrying the horizontally arranged return pulley, a movable platform provided with an upward incline, a drive shaft vertically arranged provid ed with a pulley, the endless cable extending between said pulleys and provided with excavating means arranged to slide up sald incline, and a conveyerarranged beneath the incline into which the contents of said excavating means are dumped, when on the incline, substantially as described.

2. In an excavating apparatus, the combination of a movable truck provided with a counterweight on one end and an overhanging frame at the other end provided with a horizontally arranged pulley, a movable truck provided with an upright shaft carrying a horizontally arranged pulley, means for driving said shaft, and the endless cable passing around said pulleys and provided with excavating means, substantially as described.

3. In an excavating apparatus, the combination of a support, the inclined platform carried thereby extending upwardly above the same and provided with an opening on the side having a grating, the endless conveyer arranged beneath said opening, the vertical shaft provided with a pulley and arranged above said incline, and the cable provided with excavating means and carried by said pulley and provided with the support on the opposite side of the field and means for driving said pulley.

4. In an excavating apparatus, the movable truck provided. with the inclined platform extending upwardly from the earth at a dis- 5 tance to one side of the platform to a point I above the platform and having the opening, the conveyer arranged beneath said opening, the upright frame carried by said platform, the vertically movable conveyer having one end arranged beneath said first mentioned conveyer and its opposite end supported by cables passing over said frame and attached at their opposite ends to the truck, and the vertical shaft provided with the pulley above said'incline and supporting the cable to which the scrapers are attached, said cable being supported at the opposite end of the ground by another pulley.

5. In an excavating apparatus, the combination of a platform, the inclined platform, the vertical frame, a vertical shaft supported therein having a horizontal pulley, a horizontal worm wheel on said shaft, the hOI'lZOll'. tally arranged drive shaft mounted in the frame and provided with a worm engaging said worm wheel, and a cable driven by said pulley, as'and for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
